The changelog made me hopeful that they finally added the option to switch between futa and female, but no. That’s the one thing you’re not allowed to change. They had to go out of their way to disable that option, so apparently it’s part of their creative vision or something.

Very nice graphics, animations and world and body builder, amazing. But I missed controls over sex action and in general, I hate the idea of having sex with some non-human creatures. If dev was able to make such animations with non-humans, so better he could remake this all with humans. Then game would have more success and likely be one of the best out here.

Sex with non-human creatures is the entire reason this game exists. It’s what most of the audience is here for. How would the core gameplay even work without them? Without the layer of abstraction added by the fantasy element, it would be some nightmare eugenics program where you breed people for desirable traits so you can sell them to other people.
